How do I specify the following thickness constraint in SU2


y>= 0.6(0.2969*sqrt(x)0.1260*x0.3516*x^2+ 0.2843*x^30.1036*x^4)
x is the cord position along the airfoil.


This is NACA 0012 airfoil.

Or simply, where do I place my own code to define geometric constraints. Is there any template class for this purpose or I have to also change python scripts? Any advice will be appreciated.

I simulated only the upper half of the airfoil as the case is symmetric. I generated FFD control points on the upper half of the airfoil. I set the lower bounds for these control points to 0. That way, it is constrained to move only in the positive Y direction (upwards in this case). This way the baseline shape is not violated. My simulations have worked well.


Note: BFGS cannot handle bounds and constraints. SLSQP can.
